SHIP S WINDLASS.

Specification of Letters Patent No. 28,7 16, dated June 12, 1860.

To all whom 'it may concern:

Be it known that I, A. I. GovE, of the city and county of San Franciscoand State of California, have invented a new and Improved lVindlass,which I call, Goves improved windlassg and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawings,making a part of this specification.

Figure 1 is a perspective view of the apparatus; Fig. 2 is a sectionalview of the capstan, showing its connection with the gearing; Fig. 3represents the lever and pawls.

A, represents the main deck of a vessel; B, the top-gallant forecastle;C, is a windlas similar to those in general use; D, is a capstan with adouble head; the upper head E, revolves separate from the capstan; F, isa perpendicular shaft attached at one end to the revolving capstan headE, and at the other to the bevel gear G; H, H, are

circular plates of metal, acting as crank arms, with bevel gear wheels,I, I, attached to the inner side and working in the gear wheel Gr; orinstead of the circular plates, common crank-arms may be used; K, K, arelevers upon one end, of each of which, a collar is formed as shown at L,so that they may work around the windlass; to these levers are attachedpawl P, P, which work in the ratchets R, R; S, S, are connecting (rodsfrom the levers K, K, to the circular plates, or crank arms H, H.

Operation: To work the windlass, the head E, of the capstan is made torevolve by means of the capstan bars, in the usual way, the gear wheelG, by means of the shaft F, is set in motion, working the gear wheels I,I, turning the cranks H, I-I, and by means of the connecting rods S, S,working the levers K, K, and by the pawls P, P, causing the windlass tooperate. The power thus gained by the use of the gearing, being a vastincrease over the brake windlass.

I do not claim the peculiar form of the windlass, as that may be variedto suit circumstances; I do not claim the lever K, and vthe ratchets andpawls, nor the connecting rods S, S; I do not claim the capstan with adouble head.

IVhat I claim and for which I desire Letters Patent to issue, is-

The arrangement of the gearing as represented by G, and I, I, with thecrank-plates or arms H, H, combined with the connecting rods S, S, thelevers K, K, and pawls P, P, working the windlass C; substantially asdescribed and for the purposes as herein set forth.
